"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"The job turned out great and we are very pleased. We have been using this contractor for many years and have always been completely satisfied with the work done. Before we moved to a condo, we had a three story house and he did many jobs for us from replacing the roof, to installing a sump pump in the basement."

"The kitchen was completed gutted and rebuilt within 3 weeks. Matt worked with us on every aspect of the remodel and addressed everything we had on our wish list. On all the projects Matt and his people were here every day until the work was completed to our satisfaction. When they left each day the work site was spotless. We have been happy to recommend MNB Renovations to our friends and family and plan on having Matt back when we are ready for our next project(s)."

"We hired Michael Ward to finish our basement including a full bathroom with a walk in shower and closets. Michael was a pleasure to work with. He is a professional, knowledgeable and experienced contractor who takes pride in his work. His prices are very competitive and he completed the entire job at a timely manner. We are very satisfied with the end result. The finished basement looks flawless and the new bathroom is beautiful. I highly recommend Michael and will hire him if I have any other projects in the future."

FAQs for basement remodeling projects in Unionville, PA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
